The archives KOLA_PRF.zip and KOLA_SRF.zip contain individual Ps and Sp receiver functions, respectively, calculated for the broadband seismic stations listed in RF_stations_tab.txt. Each receiver function is provided in miniSEED format and was computed following the processing techniques described by Kraft et al. (2019), Vinnik (2019), and Monna et al. (2022). For Ps receiver functions in KOLA_PRF.zip, the time window is from −50 to 200 s, where 0 s corresponds to the P-wave onset time. For Sp receiver functions in KOLA_SRF.zip, the time window is from −120 to 50 s, where 0 s corresponds to the S-wave onset time. The file names correspond to the earthquake origin times reported in the GCMT catalogue and follow the convention YYYYMMDD_HHMMSS.mseed, where YYYY is the year, MM is the month, DD is the day, and HHMMSS is the origin time in hours, minutes, and seconds, respectively. All origin times are given in UTC.
